Parade shield or buckler, circular, slightly convex, the border flat, embossed and chiselled with the allegorical subject possibly representing the Tiburtine Sibyl announcing the birth of Jesus to the Emperor Augustus. In the centre the Emperor kneels in adoration with the crown at his feet, the Sibyl on the right points upwards to a cherub holding the emblems of royalty; on the left an attendant holding a horse, and in the background a city. The surrounding border is decorated with four cartouches of the Seasons, alternating with incised scrolls; the edge is turned under, roped and bordered with a row of brass-headed rivets (modern). The shield has been repaired in several places, and appears to have suffered from rust and severe cleaning, having now a leaden appearance; it is pierced in three places for the arm and hand-hoops, and other holes have been filled in it now bears no traces of damascening or gilding.

In the Musée de l' Armée in Paris, is a burgonet and shield, richly embossed and damascened in great detail with a representation of the same subject; in this case the Sibyl points upwards to the Virgin and Child, and there are other variations (Niox, Musée de l' Armée I, pls. XLIII, XLIV).

A round target in the Armeria Reale, Turin, is decorated with the same subject but with the composition in reverse (no. F10; Mazzini, 1982, no.100).
